Struct multiboot::Multiboot [−][src]
Multiboot struct clients mainly interact with To create this use Multiboot::new()
Methods
impl<'a, F: Fn(PAddr, usize) -> Option<&'a [u8]>> Multiboot<'a, F>[src]
impl<'a, F: Fn(PAddr, usize) -> Option<&'a [u8]>> Multiboot<'a, F>Multiboot structure.
pub unsafe fn new(
mboot_ptr: PAddr,
paddr_to_slice: F
) -> Option<Multiboot<'a, F>>[src]
pub unsafe fn new(
mboot_ptr: PAddr,
paddr_to_slice: F
) -> Option<Multiboot<'a, F>>Initializes the multiboot structure.
Arguments
mboot_ptr- The physical address of the multiboot header. On qemu for example this is typically at 0x9500.paddr_to_slice- Translation of the physical addresses into kernel addresses.
paddr_to_slice translates physical addr + size into a kernel accessible slice.
The simplest paddr_to_slice function would for example be just the identity
function. But this may vary depending on how your page table layout looks like.
Safety
The user must ensure that mboot_ptr holds the physical address of a valid Multiboot1 structure and that paddr_to_slice provides correct translations.
pub fn lower_memory_bound(&self) -> Option<u32>[src]
pub fn lower_memory_bound(&self) -> Option<u32>Indicate the amount of lower memory in kilobytes.
Lower memory starts at address 0. The maximum possible value for lower memory is 640 kilobytes.
pub fn upper_memory_bound(&self) -> Option<u32>[src]
pub fn upper_memory_bound(&self) -> Option<u32>Indicate the amount of upper memory in kilobytes.
Upper memory starts at address 1 megabyte. The value returned for upper memory is maximally the address of the first upper memory hole minus 1 megabyte. It is not guaranteed to be this value.
pub fn boot_device(&self) -> Option<BootDevice>[src]
pub fn boot_device(&self) -> Option<BootDevice>Indicates which bios disk device the boot loader loaded the OS image from.
If the OS image was not loaded from a bios disk, then this returns None. The operating system may use this field as a hint for determining its own root device, but is not required to.
pub fn command_line(&self) -> Option<&'a str>[src]
pub fn command_line(&self) -> Option<&'a str>Command line to be passed to the kernel.
pub fn modules(&'a self) -> Option<ModuleIter<F>>[src]
pub fn modules(&'a self) -> Option<ModuleIter<F>>Discover all additional modules in multiboot.
pub fn memory_regions(&'a self) -> Option<MemoryMapIter<F>>[src]
pub fn memory_regions(&'a self) -> Option<MemoryMapIter<F>>Discover all memory regions in the multiboot memory map.
